  Neovim, a programmer's text editor based on Vim, provides several modes for different kinds of text manipulation.
  Pressing `i` enters edit mode. `<Esc>` goes back to normal mode, which doesn't allow regular text insertion.
  More information: <https://neovim.io>.

  Open a file:

      nvim file

  Enter text editing mode (insert mode):

      <Esc>i

  Copy ("yank") or cut ("delete") the current line (paste it with `P`):

      <Esc>yy|dd

  Undo the last operation:

      <Esc>u

  Search for a pattern in the file (press `n`/`N` to go to next/previous match):

      <Esc>/search_pattern<Enter>

  Perform a regular expression substitution in the whole file:

      <Esc>:%s/regular_expression/replacement/g<Enter>

  Save (write) the file, and quit:

      <Esc>:wq<Enter>

  Quit without saving:

      <Esc>:q!<Enter>
